OpenGL Extension Viewer is reliable software that provides information about the current OpenGL 3D accelerator, including the vendor name, implemented version, renderer name, and extensions. Many OpenGL extensions and extensions to related APIs like GLU, GLX, and WGL have been established by vendors and groups of vendors. The extension registry, which is maintained by SGI, contains specifications for all known extensions, written as modifications to appropriate specification documents. Additionally, the registry defines naming conventions, guidelines for creating new extensions and writing suitable extension specifications, and other relevant documentation.

OpenGL Extensions Viewer is a free-of-charge software that has been recognized by Softpedia as a 100% free and safe from spyware, adware, and viruses. If you want to download the latest version of OpenGL Extensions Viewer (GLview), you can do so for free from selected stores.

Extensions
Display extensions, sorted by vendor. If you have an Internet connection, you can retrieve from OpenGL.org the extensions's specifications that explain the available extensions. You can click on extension and press 'Search' for getting extension's specification from severals different databases. You can also use the left button mouse.

Display Modes
Display all supported display modes.

Pixel Formats

Report
The OpenGL diagnostic tool performs some OpenGL initialisation and graphical test. It will use the desktop resolution. So in case of slow downs or initialisation errors, use a smaller desktop resolution. 

OpenGL 1.1 : use the standard OpenGL without extension usage.
OpenGL 1.2 : OpenGL test using GL_lock_array and glDrawElement.
OpenGL 1.3 : OpenGL using GL_lock_array and multitexturing.
OpenGL 1.4 : OpenGL test using GL_lock_array and multitexturing using a DOT3 shading and an ARB vertex program code.
OpenGL 1.5 : OpenGL test using Vertex Buffer Object.
OpenGL 2.0 : OpenGL test using a GLSL 1.0 program.
OpenGL 2.1 : OpenGL test using pixel buffer object.
OpenGL 3.0 : OpenGL test using OpenGL 3.0 Forward Context (only supported under Windows).

OpenGL EXTENSIONS

A very extensive list of details of all extensions available of your system, which OpenGL functions are implemented and more.
A core feature set check also show how well from OpenGL version 1.2 to 4.0 are implemented in your system.
More than 450 extensions reported and collected since 2000!

OpenGL 1.1 / 1.2 OpenGL 1.3

OpenGL Extensions Viewer has been suggested by OpenGL.org
in the OpenGL technical FAQ (see 23.050) (**)
and by nVidia as Developer Resources.

Vulkan Extensions are available in the Vulkan Report Section

OpenGL 1.1 / 1.2

 

 

RENDERER DATABASE

A database of all known renderers for Windows and MacOSX is available. If an renderer is being updated, you can submit to the server. You can also update to the latest database directly from the application.

OpenGL 1.1 / 1.2 

FAQ

Q> I can't find the driver to load for my software that requires OpenGL 2.1. What should I do?
A> You can't download OpenGL itself, but you can download display drivers that include OpenGL. Check the version displayed by OpenGL Extensions Viewer. If it shows 'GDI Renderer', it means that something is preventing OpenGL from working. Sometimes, setting an environment variable with QT_OPENGL can resolve the issue.

Q> Will the version of OpenGL Extensions Viewer that reports '4.613572 Core Profile Compatibility 19.11.1' work for Blend, which requires OpenGL 3.3 or above?
A> Yes, it will work. The version number is the first set of figures in the version name, and in this case, it is 4.6.

Q> I downloaded the latest version of OpenGL to play a game that requires OpenGL 2.1 or above, but it only shows version 1.1 when I open it. What's wrong?
A> This means that something is preventing OpenGL from working. For example, opening an OpenGL software remotely or through a virtual machine usually doesn't work. Check OpenGL Extensions Viewer to see which version is installed, particularly the DirectX version. If you have DirectX 11, there is a good chance that OpenGL is compatible, but a software or resolution issue may be blocking it.
